Mark Zuckerberg and Priscilla Chan’s Chan Zuckerberg Initiative reorganized its science portfolio and folded EvolutionaryScale into a unified Biohub effort, hiring EvolutionaryScale’s team and naming Alex Rives head of science for a new large‑scale AI‑plus‑biology initiative. Separately, Biohub announced broader plans to scale compute, datasets and experimental platforms to build foundation models for biology — an effort positioned to accelerate drug discovery and large‑scale biological modeling by combining frontier compute, instrumentation, and AI expertise.
